Abstract
Traffic accidents are major concern even though technologies such as ITS are being develop. It is important to predict where and how traffic accidents might occur, and to know how to prevent traffic accidents. Traffic simulators that have the function of simulating traffic accidents can help users to predict them. Our goal is to make a traffic simulator which can reproduce traffic accident and can be used for simulating real city. In this paper, we develop new traffic accident models and implement them to an existing traffic simulator. We considered drivers' errors and classified them into four patterns for modeling traffic accidents. We reproduce traffic accidents in a realistic situation by modeling traffic accidents depending on the environment surrounding the driver.
